Water test

NOTE: Do not use a power washer. Use a normal garden hose with a spray nozzle or sprinkler head.

Make certain that all windows and doors are completely closed.

Water leaks into the vehicle passenger compartment cannot usually be located immediately, as the water often spreads across a large area. For this reason, the passenger compartment must be dried before the leak tests.

Any ancillary components that block the view must be removed. During the water test, the vehicle is sprayed or sprinkled with water at the suspected location of the leak. At the same time, a second person checks the passenger compartment for places where water enters the vehicle. Depending on the test and the vehicle, it may take some time before there is any sign of water entering the vehicle. We recommend laying blotting paper under the location being tested so that the water entry can be localized.

Example: Water test with sprinkler head (rain test)

Car wash test

Certain leak problems only appear in a car wash or can only be simulated there. The concerned area of the passenger compartment should be inspected with a torch during the wash procedure.

Road Test

Some leaks only appear when the vehicle is moving. If no leaks are detected during the above-mentioned tests, road tests should be carried out on wet roads:

  • At various speeds.
  • On various road surfaces (asphalt to cobbles).
  • With loaded or unloaded vehicle.
  • Driving through puddles (splash water).
